Especially in light of replication (broker-broker communication), I'm wondering if all the brokers are in the same rack and what kind of networking interfaces are used (Gigabit ethernet, Fibre Channel, etc). On 3/29/13 6:53 PM, Jun Rao wrote: We have multiple Kafka clusters, each has about 10

We have multiple Kafka clusters, each has about 10 brokers right now. Not sure about the network topology. What kind of info do you want to know? Thanks, Jun On Fri, Mar 29, 2013 at 11:47 AM, David Arthur wrote: > How many brokers are you (LinkedIn) running? What kind of network topology? > >

1. We never share zookeeper and broker on the same hardware. Both need significant memory to operate efficiently. 2. 14 drive setup is just for Kafka. We have a separate disk for the OS, AFAIK. Thanks, Neha On Fri, Mar 29, 2013 at 11:37 AM, Ian Friedman wrote: > Thanks Jun. Couple more questions

Thanks Jun. Couple more questions: 1. Do you guys have dedicated hardware for Zookeeper or do you have a few machines run both a ZK and a broker? If so, do you keep the ZK and Kafka data on separate volumes? 2. You use the 14 drive raid setup is just for Kafka data and a separate drive for the

It's more or less the same. Our new server has 14 sata disks, each of 1 TB. The disk also has better write latency due to larger write cache. Thanks, Jun On Fri, Mar 29, 2013 at 8:32 AM, Ian Friedman wrote: > Hi all, > > I'm wondering how up to date the hardware specs listed on this page are:

Hi all, I'm wondering how up to date the hardware specs listed on this page are: https://cwiki.apache.org/confluence/display/KAFKA/Operations We're evaluating hardware for a Kafka broker/ZK quorum buildout and looking for some tips and/or sample configurations if anyone can help us out with s
